I04 THE FAMILY DOCTOR How to Avoid Disease. There are various ways in which disease ma}^ be avoided. One is not to expose our- selves to contagion or injurious influences. We need to be careful of the food we eat, the water we drink, even the air we breathe, for all of these, as above shown, are prolific sources of the germs of disease, We must also keep away from those afflicted with con- tagious diseases, or, if obliged to enter their presence, take precautions to avoid in- fection. This danger is now taken in hand by the health authorities of cities, patients of this character being removed to special hos- pitals, or, if kept at home, the yellow placard of warning is conspicuously dis- played. Only physicians and nurses — who are supposed to know how to take care of themselves — are permitted to enter the sick- room, or even the house in cases of this kind. A second and highly important method of avoiding disease, whether infectious or from organic weakness, is to strengthen the system by dint of suitable exercises ; seek to breathe only fresh and pure air, adapting the clothing to the climate and the bodily needs, and in other ways endeavoring to harden the body and to enable it to defy the insidi- ous assaults of disease. Muscular Exercise. Exercise of all parts of the body is an absolute necessity for the maintenance of perfect health. If a steam-engine is allowed to stand idle it will soon rust and get out of order. Similarly, if the body has no work to do, it will become too fat, and the mus- cles will waste and get flabby, the heart will become weak, the circulation slow and fee- ble, the blood will not be properly aerated, poisonous products will accumulate in the l3ody, the complexion will be pale, and the intellect dull, and if the brain is not regu- larly exercised the person will merely de- velop into a muscular animal, no better than a savage ; he will be stupid, ignorant, and uninteresting both to himself and to others. The effect of regular muscular exercise is to expand the lungs, to increase the ,568 amount of oxygen taken in and the carbon dioxide breathed out ; the sweat is increased, and so exercise helps to get rid of waste matters from the body. The heart is strengthened, the blood is more aerated, the muscles grow larger, harder, and more ac- tive, the appetite and digestive powers in- crease, the body is kept warm, and the brain is more active and bright as a result of the general health being so good. During exer- cise more food is required and much pure air.
